(onset-45y This invention 1 relates to 1 apparatus fo test ingliquids; niere particularly a tee ing kit to used in t leterinination of ity oia l uidsuchesoil. and has for its priomary object the provision an iproved, cornpact kit w .h can readily ed by an operator from place to place and in which the delicate instruments to be used will be protected from breakage.

Another object my invention sion of a wind deflecting member 10" the provifor shielding the instruments while readings are being taken.-

For a better understanding of my invention,

reference may be had to the accompanying drawing, in which Fig.1 is a perspective View of my testing kit assembled for carrying; Eig.

2 is a perspective view similar to "Fig. 1 but.

"with the wind deflector removed; Fig. 3 is a perspective view of oil container; 4, 5 and 6 are perspective views respectively of the instrument case, wi ector and cap for t instrument case; while rig. 7 is a pers ective view with parts broken showing the method of assembling the kit.

Referring to the drawing, an elongated receptacle 10 serves as the conta ner or jar in which the oil or other liquid to be tested is held during a test, and also a; a carrying case for the instruments to be used. The receptacle or 10 is preferably square in be made of any suitable material, alt ough aluminum is preferred, due to its strei stir and light-- "ness. Secured to the lower end of the jar 1c is a base 11, which may be of the same material as the jar, but which is larger cross-section and preferably non-circular Suitably secured to one side i the jar i a handle 30 to be used in carrying the kit place to place.

An instrument case 13 slightly longer than the jar 1G and of the same general shape but 71, slightly smaller in section, is arranged to have a sliding fit and to be telescoped within the jar.

e grav provided with-fa parunent case which are led k111i). .ots, such -as a pair hydromeahydronieters may be further on- -tubular members 16 soi't fiber or felt, 11111811113 oi the case and serve to protect the hyfrom breakage. during transportation. interlocking grooves 17 and 18 are ctively in the jar 10 and the instrument case 1 and aid in holding the instrument case sec-rely in position. A cap member 19 slightly larger in section than the instrument case 13 serves to fit over and close the upper end oi the in are not in use. Preferably, the compartments of the instrument case 13 are lined with a soft material such as felt (not shown) to further protect the hydrometers 15. It will thus be observed when the hydrometers 15 are inserted in the tubes 16 and the cap member 19 placed on the instrument case 13 a receptacle is thus provided which will eiiectively protect and prevent breakage of the hydrometers when they are not in use.

In order to prevent the wind from disturbing the hydrometer and moving or tilting it in the oil so that inaccuracies or" the readings will result, I have provided a wind deflector comprising a short tubular member 20 of the same section but slightly larger than the jar 10. The wind deflect-or 2G is open at the lower end and substantially open at the upper end except for the provision of corner steps 21, which serve to limit the movement of the wind deflector when it is telescoped over the upper end of the jar, as shown in Figs. 1 and '7. The cap member 19 and the Wind deflector 20 are also provided with interlocking grooves 22 and 23 respectively to cooperate to hold these members in position. One side of the Wind deflector 2-0 is provided with an elongated sight opening or Window 24.

When it is desired to carry the kit from one place to another, the hydrometers 15 are inserted in the tubes 16, the cap member 19 is then placed over the case 13 and the instrument case 13 then telescoped Within the jar 10 as is shown in 3 2. The wind deflector 20 is then telesooped over the upper en. of the jar, as is shown in Figs. 1 and 7, and the kit may then be carried by means of th handle 12. When the operator or oil gauger is ready to make a test he removes the wind deflector 20 and withdraws the instrument case from the jar 10. The sample of oil 7 side wall of to be tested is then placed in the jar and the hydrometer 15 is removed from the instrument case 13 and floated in the oil. If sufficient Wind is blowing to cause a deflection of the stem of the hydrorneter and thus an inaccurate reading, the gauger slips the wind deflector 20 over the upper end of the The stem of the hydrometer 15 is then protected from the wind and Will stand erect. The operator can then obtain his reading by looking through the Window 24 in the the wind deflector 20. i

From the foregoing description it will be ob served that I have provided a liquid testing or gauging kit which is compact and has a minimum number of parts. When readings are being taken the enlarged base 11 serves to hold the jar upright and in case the jar should be overturned, the non-circular shape of the jar and the base will prevent rolling, even though the jar should. be resting on an inclined surface, such as the roof oi"; an oil tank.

While I have described my invention as em bodied in concrete form and operating in a specific manner in accordance with the provi sions of the patent statutes, it should be understood that I do not limit my invention thereto, since various modifications thereof will suggest themselves to those skilled in the art without departing from the spirit of my invention, the scope of which is set forth in the annexed claims.

1. In combination with a jar for containing a liquid to be tested, a wind deflector having sliding, telescoping engagement with one end of said jar, said deflector being provided in one side thereof with a sight opening through which observations may bemade.

2. In combination with an elongated jar for containing a liquid to be tested, said jar being of non-circular cross-section and provided with an enlarged base member to aid said jar in standing in an upright position, a wind deflector having the same shape in cross-section as said jar and having sliding engagement with one end of said jar, said deflector being provided in one side thereof with a sight opening through which the interiors of said jar and deflector may be observed.
